Study Notes
Tensile Testing Objective
- Determine a material's mechanical properties under tensile load.
- Mechanical properties inform material suitability for resisting applied forces.
Tensile Testing Theory
- Examines forces and material behavior under tension.
- Directly measures:
- Maximum Load: Highest force the material withstands before failure.
- Maximum Elongation: Change in length from the original gauge length.
- Reduction in Area: Change in cross-sectional area during deformation.
- Derived properties calculated from measurements:
- Stress: Force applied per unit area.
- Strain: Deformation per unit length.
- Yield Strength: Stress at which the material begins to deform permanently.
- Ultimate Tensile Strength: Maximum stress the material can withstand before failure.
- Young's Modulus: Measure of stiffness, representing the ratio of stress to strain in the elastic region.
- Ductility: Degree of plastic deformation before failure.
- Toughness: Ability to absorb energy before fracture.
Tensile Testing Applications
- Material scientists use tensile testing for research and development of new materials.
- Research institutions use tensile testing to study material behavior.
